RSEG is actively engaged in research on 1) improved methods for estimating unknown parameters from multivariate data, particularly from generic blind data, data obtained by passive multi-spectral imaging remote sensing satellites, and wireless communications, 2) advancing the state-of-the-art of passive microwave and infrared remote sensing of the atmosphere from aircraft and spacecraft, particularly for purposes of sounding atmospheric temperature, humidity, and precipitation profiles, 3) use of satellite data to characterize the earth, and particularly its global precipitation, and 4) devlopment of self-organizing RF spectrum allocation techniques for internet and other applications. The remote sensing work also includes development and operation of passive microwave spectral imagers at millimeter and sub-millimeter wavelengths, and development of the associated calibration techniques for aircraft and spacecraft. The wireless communications program includes development and utilization of multiport sensors for characterizing wireless propagation and spectrum use.

Currently the three most active flight programs involve: 1) the NAST-M passive imaging microwave spectrometer, which can fly on the NASA ER-2 and Proteus aircraft, 2) the Advance Microwave Sounding Unit (AMSU) on the NOAA-15, NOAA-16, and NOAA-17 weather satellites, and 3) the AIRS/AMSU/HSB sounder on the NASA Aqua satellite. Links to work with these systems are available.

Prior and related work has also involved video image processing, optical astrometric interferometers, multi-mode controlled structures, design of experiments, manufacturing process characterization and optimization, pulsar radio astronomy, planetary radio astronomy, communications network architecture, and other topics.
